Ultimate Edition 4.6 x64 XFCE

I downloaded and tried Ultimate Edition 4.6 x64 XFCE. I am truly impressed ! I've really never been too taken with XFCE, but this implementation with UE4.6 actually rocks. I tried to get the distro to install in Virtualbox but it stops at Welcome to Ultimate Edition 4.6 Build and wouldn't go any further. I haven't had any luck installing any 4.6 in Virtualbox. I,m running Ultimate Edition 4.6 x64 Gamers on this machine and love it. I have a spare 300 GB drive that I am going to try installing the XFCE version on today. I may have a problem after that deciding which of the two to run as my main os if all goes well. Thanx "O' Imperious Leader", as always you never cease to amaze me. Oh, before I forget this little problem, I find that in all of the recent distros, when I open Appearance to change my desktop background or theme, one of my processor cores maxes out at 100% and stays that way even after ending the application until I reboot. That's the only app that happens with. Everything else runs smooth as silk. Awesome!!
